Assembling the decoration is definitely the most time-intensive task of the tutorial.
To start, glue each star-like baseplate to the TroGlass Satins circle. Be sure that the two large pieces are positioned neatly edge-to-edge. Then, if you haven't already, flip the decoration and get rid of the protective foil. Fix each TroLase Foil semi-circle in place and then apply each piece from the different materials.
Glue the finished product to the white baseplate only if you are sure that you have positioned the pieces correctly. It can be handy to keep a copy of the finished picture on hand. This image can be found in the provided download document.
After every piece has been fixed in place, you can mount the finished piece to a wall with mounting devices.
